No power; turbo / fuel, need help
I recently bought a 92 auto 4wd ext cab. It has been nothing but a nightmare so far. Here are the symptoms. Runs smooth, starts with a half turn of the key. Truck has barely any power. Turbo kicks in and out at say a third throttle running down the road steady. Sometimes turbo will not spool up at all, other times it spools and pulls well. No black smoke ever. I replaced the lift pump, and it was worn out, spring shot and it could not manually pump at all. Replaced fuel filter, when I did this the plate above it came out as well. This seemed to only go in one way and there are no leaks. Lift pump / filter made no difference.
Could the injection pump be shot having to had made up for the weak lift pump? Would that cause the turbo not to work? Any ideas / help is greatly appreciated.
